PCRET to install 368 biogas plants in rural areas

Pakistan Council of Renewable Energy Technologies to install 368 biogas plants in rural areas
ISLAMABAD - Pakistan Council of Renewable Energy Technologies (PCRET) will install 368 Biogas plants in different rural areas by the June 2012 under the project “Development and Promotion of Biogas Technology for meeting domestic fuel needs of rural areas and production of Biocfertilizer”.
This project was launched in 2008 through which 2500 family size Biogas plants are to be installed in the country, out of these 2132 plants have been installed and the remaining will be installed by end of financial year 2011-12. Biogas plant is a device used for converting fermentable organic matter, particularly cattle dung, into a combustible gas (Biogas) and fully matured and enriched organic fertilizer. Read more

Bio Gas Fuel Cells Run On Waste Products and are essentially

Bio Gas Fuel Cells Run On Waste Products and are essentially “GREEN” in the utmost sense since they take advantage of using what is otherwise unused.  Biogas fuel cells essentially “clean” in some regards the waste in waste water treatment plants and in this process an electric current is created which can be harnessed as useable power.Bio Gas Fuel Cells Run On Waste Products and are essentially “GREEN” in the utmost sense since they take advantage of using what is otherwise unused.  Biogas fuel cells essentially “clean” in some regards the waste in waste water treatment plants and in this process an electric current is created which can be harnessed as useable power.
Initially conceived as an off shoot of the technology featured as part of the Apollo Space Missions, fuel cells take advantage of a chemical reaction (i.e., non-combustion) in which an electric current is produced.
Now fast forward to 2012, dozens of waste water treatment plants are being retrofitted and redesigned as Bio Gas Fuel Cells which produce electricity to power their own operations.   Fields of biogas creating algae are being grown in the Arizona Desert and in other places around the planet.  This biogas can be chemically “perfected” to run certain types of fuel cells.  Hence, we have what can be viewed as a truly renewable energy source.  In this scenario, I believe fuel cells rank well as a true green energy solution.
Could the traditional oil/gas fields worldwide be replaced by “new fields” which produce a new fuel type created in abundance by biofuel producing algae?  Time will tell.

Magnetic Levitation

 

description

Here is a very cheap and high stable levitation schematic for beginners it uses only to transistors and few other parts they are all easily available in hole world instead of those pricey and complicated integrated IC schematics take hole day to built but this project is not only cheap but easy to built in minutes coil is made in this project from scrap I took primary winding wire from an old wall mount 12v power supply and Use sewing machine bobbin for coil winding there is no counting for turns just make sure wind bobbin full until it reaches its outer radius secure it with electrical tape make sure both ends of winding are enough length to solder it to project board use bolt as core which fits in bobbin hole make sure bolt must be twice in length than bobbin so that you can nicely tighten your coil to frame for further info see fig2.
